upper endslof "the bolts are screw-threaded ereby having a piston rod 23 extending through a stuffing box 24 in one end of the cylinder.

The forward end portion 25 of the piston is of reduced diameter and extends through the cross head 16,.a nut 26 being mounted upon the screw-threaded end of the piston, whereby the cross head is secured upon the reduced portion 25 'between'the nut and the shoulder 27 between the reduced portion and the main portion of the piston.

The cross head has upwardly extending ears 28 at its opposite ends between and through these earsis 'a horizontal rod 29. A pair of links 30 is'journaled at one end upon end upon a rod 31-which extends through downward extensions 82 at the rear-end of a pusher member Journaled upon the ends of the rod 31 at the outer sides of'the extensions 82 is a pair of flanged wheels 34 which travelupon the tracks 15.

The pusher member is cast in one piece and comprises extensions '32 integral with their rear ends and having the flat horizontalcross-bar 36 connecting their forward ends. ward extensions 32 verse bar 37. Integral with the extensions 32 are forwardly extending arms 38 substantially parallel with but spaced below the sides The normal position-ofthepusher memher is shown'in fulllines in Figures-1 and 2, in which'position of the pusher the piston 22 is at the rear end of thecylinder- 18. this position of the pusher member, the cross bar 36 "at the forward end thereof rests upon rollers 39 journaled between collar-s LO-on a shaft all arranged between the forward roller 6 and the roller 7 of the delivery table and journaled in bearings 4C2; A gear 4:3is mounted upon one end of this shaft and meshes with gears ll and on the corre sponding end of the shafts 46 and 47 of the rollers 6 and 7, whereby-the drive is transmitted from the roller 7 to the roller 6. The rollers 7, 8 and 9 are each formed in'three parts to provide annular spaces 48 to accommodate the sides 35 of the pusher member.

The operation of the apparatus is substan tially as follows:

and extending this rod and at the othersides 35 having the downward The down-t are connected by a trans- 7 downward In the normal position of the pusher mechanism as shown in full lines in the drawings, the pusher member 33 is slightly below the line of delivery of the material and the flanged wheels 3% are at the rear tapered ends of the tracks 15. Vhen it is desired to push a crop end through the shear, pressure fluid will be admitted to the rear end of the cylinder 18, therebycausing the piston 22 to move to the forward end of the cylinder and move the pusher member 33 forwardly. During the initial forward movement of the pusher member the flanged wheels will ride up the inclined rear ends of the tracks 35, thereby elevating the rear end of the pusher member. When the forward end of the pusher member engages the surface of the roller 7 this end of the member will also be raised, thereby bringing the forward end of the pusher member in the same plane as the crop end resting on the lower knife block. During the further advance of the pusher member the forward edge of the cross-bar 36 will engage the rear edge of the crop end and the latter will be pushed completely through the shear as the pusher member completes its advancing movement. The ad vanced position of the pusher member is shown in dotted lines in Figure 2. Upward tilting movement of the pusher member about the rod 31 as the pusher member is advanced is limited by the engagement of the arms 38 with the shaft 49 of the roller 8. The pusher member is retracted by admitting fluid to the forward end of the cylinder 18.

lVhile I have shown and described the preferred embodiment of my invention, it will be understood that the invention may be otherwise embodied without departing from the spirit of the invention or scope of the appended claims.

claim 1. The combination with a; shear and a roller table for delivering material thereto, of means associated with said roller table and normally positioned below the delivery line thereof for pushing the crop ends of material through the shear, substantially as described.

2. The combination with a shear and means for delivering material through the shear, of means normally positioned below the deliv ery line of the material for pushing the crop ends of the material through the shear, and means for operating said pusher means, including means for elevating said pusher means as it is advanced, substantially as described.

3. The combination with a shear and delivery means for passing material through the shear, of means associated with said delivery means for pushing the crop ends of the material through the shear, comprising a pusher member supported below the line of delivery of the material for reciprocation towards and from the shear, and means for operating said member, substantially as described.

4. The combination with a shear and means for delivering material thereto, of means associated with said delivery means for pushing the crop ends of the material througn the shear, comprising tracks arranger below the delivery means, pusher means having supporting wheels running on said tracks, and means for reciprocating said pusher means towards and from the shear, subs ntially as described.

5. The combination with a shear and means for delivering material thereto, of means associated with said delivery means for pushing the crop ends of the material through the shear, comprising tracks arranged lyelow the delivery means, a pusher member having its material engaging portion normally positioned below the delivery line of the material and having wheels running on said tracks, and means for reciprocating said pusher member towards and from the shear, said delivery means being arranged to eii'ect raising of the material engaging portion of the pusher member during forward movement thereof, substantially as described.

6. The COHlbilltltlOll with a shear and a roller table for delivering material to the shear, of means associated with said table for pushing the crop ends of the material through the shear, comprising a pusher memher, and means for reciprocating said member towards and from the shear, certain of the table rollers being formed in spaced sections to accommodate said member therebetween, substantially as described.

7. The combination with a shear and a roller table for delivering material to the shear, of means associated with said table for pushing the crop ends of the material through the shear, comprising a pusher member normally positioned below the delivery line of the material, certain of the table rollers being formed in spaced sections to accommodate said member therebetween, substantially as described.

8. The combination with av shear and 21 roller table for delivering material to the shear, of means associated with said table for pushing the crop ends of the material through the shear, comprising a pusher member normally positioned below the delivery line of the material, certain of the table rollers being formed in spaced sections to accommodate said member therebetween, tracks arranged below the delivery table, wheels carried by said member adjacent one end thereof and running on said tracks, means for reciprocating said member towards and from the shear, and supporting means engaging the lower side of said memill) her, said tracks having cam portions engaged by said wheels to effect raising of the rear portion of said member during forward movement thereof, the forward end of the pusher member being raised by engagement with one of the table rollers during such forward movement, substantially as described.
